Wording matters: why maybe physicists should reconsider using terms like 'probability' and 'uncertainty' when talking about quantum mechanics.

Elementary particles are neither waves nor (point-like) particles, nor are they both. The most general and unassuming description we have of their behaviour is formulated in terms of complementary states consisting of properties defined not in terms of specific values but as 'possibilities' (degrees of freedom). Interacting particles form a system wherein each particle's possible states are inseparably defined in such a way that the system as a whole "makes sense", and this is termed 'entanglement' between particles.
